The city of Carmel, Ind., has vans for plowing snow, salting streets, and carrying landscaping tools. But one particular cherry-red pickup can do anything no other motor vehicle can: deliver its very own hydrogen.
A 45-kilogram metal box sits in the bed of the perform truck. When a driver starts off the motor, the machine mechanically starts concocting the colorless, odorless fuel, which feeds into the engine’s consumption manifold. This prevents the truck from guzzling gasoline until finally the hydrogen offer operates out. The pickup has no fuel-mobile module, a common part in most hydrogen automobiles. No higher-pressure storage tanks or refueling pumps are wanted, possibly.
